Question
The circuit shown in the figure below is connected for 2.50 min. (Assume R1 = 7.70 ?, R2 = 2.60 ?, and V = 10.0 V.)
(a) Determine the current in each branch of the circuit.
(b) Find the energy delivered by each battery.
(c) Find the energy delivered to each resistor.
(d) Identify the type of energy storage transformation that occurs in the operation of the circuit.
Explanation / Answer
a) I) middle = 4/6 = 0.67 A up
I ) right = 10/5.6 = 1.79 A up
so I) left = 1.79 + 0.67 = 2.46 A down
c) energy delivered to resistors = i2 R
So 7.7 ohm = 46.6 J
5 OHM = 2.24J
1 OHM = 0.45 J
3 OHM = 9.61J
2.6 OHM = 8.33J
